Simple problem: Can't expand the main form to full size

[clark_x_zhang]

Hi guys,
I've a simple problem. I cant's expand the main form to full size. In particular, I can't drag down the bottom edge of the main form. The first picture is the main form that I have. The second picture (from the manual) is the view of the main form I want. Can you tell me how to expand the main form?
Thanks,
C

It looks like you have the Windows font sizes set higher than 100%. The game is only playable with the Windows font size set to 100%.
